Streaming media refers to multimedia for playback using an offline or online media player that is delivered through a network. Media is transferred in a "stream" of packets from a server to a client and is rendered in real-time; this contrasts with file downloading, a process in which the end-user obtains an entire media file before consuming the content. Streaming is presently most prevalent in video-on-demand, streaming television, and music streaming services over the Internet.

A digital library is an online database of digital objects that can include text, still images, audio, video, digital documents, or other digital media formats or a library accessible through the internet. Objects can consist of digitized content like print or photographs, as well as originally produced digital content like word processor files or social media posts. In addition to storing content, digital libraries provide means for organizing, searching, and retrieving the content contained in the collection. Digital libraries can vary immensely in size and scope, and can be maintained by individuals or organizations. The digital content may be stored locally, or accessed remotely via computer networks. These information retrieval systems are able to exchange information with each other through interoperability and sustainability.
In copyright law, the legal status of hyperlinking and that of framing concern how courts address two different but related Web technologies. In large part, the legal issues concern use of these technologies to create or facilitate public access to proprietary media content — such as portions of commercial websites. When hyperlinking and framing have the effect of distributing, and creating routes for the distribution of content (information) that does not come from the proprietors of the Web pages affected by these practices, the proprietors often seek the aid of courts to suppress the conduct, particularly when the effect of the conduct is to disrupt or circumvent the proprietors' mechanisms for receiving financial compensation.

Sci-Hub is a shadow library website that provides free access to millions of research papers, regardless of copyright, by bypassing publishers' paywalls in various ways. Unlike Library Genesis, it does not provide access to books. Sci-Hub was founded in Kazakhstan by Alexandra Elbakyan in 2011, in response to the high cost of research papers behind paywalls. The site is extensively used worldwide. In September 2019, the site's operator(s) said that it served approximately 400,000 requests per day. In addition to its intensive use, Sci-Hub stands out among other shadow libraries because of its easy use/reliability and because of the enormous size of its collection; a 2018 study estimated that Sci-Hub provided access to 95% of all scholarly publications with issued DOI numbers, and on 15 July 2022, Sci-Hub reported that its collection comprised 88,343,822 files.
